METAL WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 765,845, dated July 26,1904.

Application filed May 4, 1904. Serial No. 206,363. (No model.)

To all whom it may concern.-

Be it known that I, HUGH E. KENNY, a citizen of the United States,residing at Detroit, in the county of IVayne and State of Michigan, haveinvented certain new and useful Improvements in Metal feather-Strips, ofwhich the following is a specification, reference being had therein tothe accompanying draw- 1ngs.

This invention relates to an improvement in metal weather-strips; and itis embodied in the construction presently to be described, and definedin the claims.

Heretofore metal weather-strips have been made with a flat base flangeor flanges and a raised sealing-rib formed of the metal folded uponitself. One of the objects of the flat base is to provide for securingthe strip in the runway of the window, tacks or small nails usuallybeing employed, which are passed through the Zinc or brass of which thestrip is made. Another object of the flat base is to form a metallicsurface against which the sash slides, thereby preventing to a largeextent the sticking of the sash. It has been found, however, that owingto the extent of contact-surface of the strip when a sash fits closelyor swells in wet weather the sash will bind, the friction between thebase of the strip and sash being too great to permit an easy movement ofthe sash. Again, when the flat base is employed and nails or tacks aredriven through the same their heads often protrude and interfere withthe proper working of the sash and often damaging it.

The object of my invention is to provide a metal strip which willovercome the objections above mentioned, and to accomplish the object Ipreferably provide a strip with a base flange or flanges, which have arelatively small longitudinal rib or ribs which project outward,preferably, and form rubbing or contact surfaces with which the edge ofthe sash contacts, thereby reducing materially the friction andrendering the sash easy to operate.

In the accompanying drawings are shown several forms of metal stripembodying the invention; but it is to be understood that various othermodifications and changes can be made 5 0 without in the least departingfrom the nature and principle of the invention.

Figure 1 is a perspective view of a preferred form of strip. Fig. 2 is across-section through a part of sash and frame, showing the stripapplied; and Figs. 3, 4, 5, 6, and 7 are variations or modifications.

In the drawings, A designates the frame, and B the sash, which latter isgrooved at b to receive the weathering rib or flange of the metalweather-strip in the usual manner. C designates the metal strip, formedwith an attaching-base and the return-bend sealingrib 0. The base orattaching flanges are formed with small outwardly-projecting rub- 5 bingribs 0, the same extending the length of the strip. These rubbing ribsengage the sash and serve as surfaces on which the sash slides in itsup-and-down movement, thereby offering but small resistance to suchmove- 7 ment. Strips, as described, also serve as filling-strips to takeup the space between the sash and frame, and thereby prevent unnecessarymovement of the sash from right to left.

In Fig. 3 the strip C is shown as having a plurality of rubbing ribs 0on opposite sides of the sealing-rib.

Fig. 4 shows a strip C having base-flanges of different width and eachprovided with rubbing ribs 0 Fig. 5 shows a corrugated type of flangedstrip, the corrugations being indicated at a.

Fig. 6 shows a strip C with a single-ribbed flange 0" at right angles tothe sealing-flanges, and Fig. 7 shows a strip C having flanges 5 formedwith relatively short rubbing ribs 0 interspersed throughout the flange.

In applying the strip the tacks or nails may be driven through theflanges between or outside the rubbing ribs, their heads being 9 belowthe ribs, so that no uneven projections will interfere with the movementof the window.

Manifestly other forms of rubbing projections can be employed. The termrubbing rib is employed herein to distinguish the construction from astrip having a plurality of sealing ribs or flanges.

Having thus described the invention, What is claimed as new, and desiredto be secured by Letters Patent, is

1. A metallic Weather-strip having an at taehing-base and a sealingflange or rib, the base being provided With a series ofoutwardly-projecting rubbing surfaces.

2. A metal Weather-strip consisting of a base-flange and asealing-flange, the base- 10 flange having a longitudinal rubbing ribthereon.

3. A metal Weather-strip consisting of a base-flange and a sealing-rib,the base-flange having a plurality of rubbing ribs extending 5 outtherefrom.

4. The combination With a frame, of a sash HUGH E. KENNY.
